McKinney 1458 4x4 Five-Knuckle Plain Bearing Full Mortise Butt Hinge | Residential Weight

The McKinney 1458 is a 4-inch x 4-inch, five-knuckle, full mortise, residential weight, plain bearing butt hinge designed for light interior residential and light-commercial door applications. As a full mortise hinge, both leaves are recessed — one into the door edge and one into the door frame — delivering a clean, flush installation that is standard on wood and hollow-metal door systems alike. The five-knuckle configuration provides a classic, traditional silhouette well suited to both residential and light-duty commercial environments. The hinge is field reversible, making it suitable for either hand without the need for separate left-hand or right-hand SKUs.

Institutional Grade Features & Benefits

• Full Mortise Design: Both leaves mortise flush into the door and frame for a seamless, professional finish that keeps the hinge profile low-profile and out of the door swing path.
• Five-Knuckle Construction: The five-knuckle barrel delivers a refined, traditional aesthetic — a widely specified style on residential and light-commercial door openings.
• Plain Bearing Operation: Engineered for residential weight door applications, the plain bearing pivot is an economical, reliable choice for lighter interior doors that do not require heavy-duty or anti-friction ball bearings.
• Field Reversible: The hinge can be re-handed on site to accommodate either left-hand or right-hand door swings, reducing inventory requirements and simplifying job-site logistics.
• Residential & Light-Commercial Weight Rating: Sized and rated for lighter interior doors typical of residential construction and light-duty commercial projects, keeping the specification right-sized and cost-effective.
• 4 x 4 Inch Leaf Dimensions: The 4" x 4" leaf size is a widely used standard dimension compatible with common door thicknesses and widths found in residential and light-commercial construction.
